 HasDigit
 determine if a string has a decimal digit

 Calling Sequence HasDigit(s)

Parameters

 s - string; string to test

Description

 • The HasDigit(s) command determines whether s has a decimal digit. A character is a decimal digit if it is one of the following:

 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

 • If s has a decimal digit, HasDigit returns true. Otherwise, false is returned.
 • All of the StringTools package commands treat strings as (null-terminated) sequences of $8$-bit (ASCII) characters.  Thus, there is no support for multibyte character encodings, such as unicode encodings.

Thread Safety

 • The StringTools[HasDigit] command is thread-safe as of Maple 15.
 • For more information on thread safety, see index/threadsafe.

Examples

 > $\mathrm{with}\left(\mathrm{StringTools}\right):$
 > $\mathrm{HasDigit}\left("abcdEFG"\right)$
 ${\mathrm{false}}$ (1)
 > $\mathrm{HasDigit}\left("abc123dEFG"\right)$
 ${\mathrm{true}}$ (2)
